Table 3. Maximum External Source Impedance Without 16-Bit Gain Error
Note 12: V
Note 13: C
Note 14: Assume ±3 sigma peak-to-peak variation; noise-free resolution means no code flicker at given bits’ LSB.
Table 2. Peak-to-Peak Resolution
Note 15: 2pF parasitic capacitance is assumed, which represents pad and any other parasitic capacitance.
